次のように変更でき、私の環境で動作しています。Drive:\ app \ Administrator \ product \ 11.2.0 \ dbhome_1 \ NETWORK \ ADMIN
listener.ora
-
前
LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS =(PROTOCOL =IPC)(KEY =EXTPROC1521))(ADDRESS =(PROTOCOL =TCP)(HOST =localhost)(PORT =1521))))
-
後
LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS =(PROTOCOL =IPC)(KEY =EXTPROC1521))(ADDRESS =(PROTOCOL =TCP)(HOST =192.168.50.90)(PORT =1521))))
tnsnames.ora
-
前
LISTENER_ORCL =(ADDRESS =(PROTOCOL =TCP)(HOST =localhost)(PORT =1521))
ORCL =(DESCRIPTION =(ADDRESS =(PROTOCOL =TCP)(HOST =localhost)(PORT =1521))(CONNECT_DATA =(SERVER =DEDICATED)(SERVICE_NAME =orcl)))
-
後
LISTENER_ORCL =(ADDRESS =(PROTOCOL =TCP)(HOST =192.168.50.90)(PORT =1521))
ORCL =(DESCRIPTION =(ADDRESS =(PROTOCOL =TCP)(HOST =192.168.50.90)(PORT =1521))(CONNECT_DATA =(SERVER =DEDICATED)(SERVICE_NAME =orcl)))
その後、 OracleOraDb11g_home1TNSListenerを再起動します サービスとOracleServiceORCL サービス。
